Zurich	Zurich Patch 10 MCP server support in ServiceNow Studio Connect Build Agent to external MCP servers in ServiceNow Studio. Previously, MCP server connectivity was only available in the ServiceNow IDE. Additional MCP server integrations Integrate Build Agent with newly supported MCP servers. Access update sets from Build Agent View update sets created by Build Agent from within the chat panel in ServiceNow Studio. Each checkpoint includes a button that opens the relevant update set in a new tab. UI validation tool in ServiceNow Studio Validate user interface output during app creation with the UI validation tool in Build Agent, now available in ServiceNow Studio. Search retrieval tool support Use the Search retrieval tool to enable agents to fetch and present relevant information from configured data sources in response to user queries. Agents can surface knowledge articles, catalog items, and other indexed content directly within the agentic workflow, reducing the need for users to navigate to separate search interfaces. Support for more file types Upload more types of files to Build Agent to describe what you want to build, including images, documents, and text and code files. Zurich Patch 9 MCP Client integration Connect Build Agent to external MCP servers to bring tools and data sources directly into your build workflow. External resources participate alongside Build Agent on the ServiceNow AI Platform, which helps reduce context switching and manual data transfer between tools. Create workflows, agents, and skills Turn business requirements into fully configured agents, skills, and agentic workflows for your custom applications. Build Agent inspects the existing tables, roles, business rules, and metadata in your app to create tailored in-app agents and tools. Test Agent for Build Agent Use Test Agent to execute Automated Test Framework (ATF) tests right from the Build Agent chat panel for test artifacts created in the same session. When tests fail, the generated tests and test results are saved in the standard ATF record tables and can be scheduled for continued regression testing for the app. If tests are edited by the test agent after troubleshooting, those edits are automatically saved to the test records. UI validation tool Validate user interface output during Build Agent app creation in the ServiceNow IDE using the integrated UI validation, which runs Playwright-based UI checks on Cloud Runner and surfaces failures with diagnostic context directly in the Build Agent panel. Semantic search for instance artifact discovery Use semantic search in Build Agent to locate relevant instance artifacts, including tables, scripts, and business rules during build and edit tasks. Find files, applications, and knowledge on your instance based on meaning instead of exact keywords. Additional model support Choose the provider and model that fits your organizational needs in Build Agent, which now supports Anthropic Claude on AWS Sonnet 4.6 and Azure OpenAI GPT 5.4. Expanded metadata support Work with more metadata types in Build Agent, which now supports flows, Service Catalog configurations, inbound email actions, dictionary overrides, choice lists, condition builder query conditions, and enhanced Service Portal capabilities. Contextual launch for Build Agent Include context from ServiceNow Studio tabs and component preview screens when you open Build Agent, which helps reduce the need to manually search for and specify context in the chat panel. Zurich Patch 8 Additional metadata support Work with more metadata types in Build Agent, which now supports email. Zurich Early Availability Build Agent in ServiceNow Studio Access Build Agent in ServiceNow Studio to build apps conversationally in a consolidated development environment. Improved LLM support Use AWS Claude Opus 4.6 and Sonnet 4.5 in Build Agent for contextual conversations. New metadata support Work with more metadata types, as Build Agent now supports the following: Email integration List controls Service Catalog items UI components UI policies UI views Workspaces
